An atom is made up of 3 sub-atomic particles: the proton, neutron and electron. A proton has a relative mass of 1, a relative charge of +1 and is located in the nucleus. A neutron has a relative mass of 1...

The relative mass of a proton is 1. The relative mass of a neutron is 1. The relative mass of an electron is 1/1840 (accept 0).

(1) First, write out the equation if it is not given: N₂ + 3H₂ ---> 2NH₃ (2) Calculate the moles of nitrogen in the reaction using the information you have; in this cas...

Magnesium atoms lose two electrons from its outer shell, thus form positvely charged ions with a charge of 2+. These 2 electrons are transferred to and gained by a diatomic molecule of chlorine atoms - ea...

It is a giant lattice structure. Sodium ions (Na+) are positively charged and chloride ions (Cl-) are negatively charged. There is ionic bonding between - strong electrosatic forces of attraction between ...
